Recently at DevSKiller.com  we've decided to move majority of our stuff to simple containers. It was pretty easy due to use of Spring Boot uber-jars, but the problem was in  NewRelic  agents which should have to be included separately. That caused uncomfortable situation so we decided to solve it by including NewRelic agent into our uber-jar applications. If you also want to simplify your life please follow provided instructions :) At first we have to add proper dependency into our pom.xml descriptor: <dependency> <groupiId>com.newrelic.agent.java<<groupId> <artifactId>newrelic-agent</artifactId> <version>3.12.1</version> <scope>provided</scope> </dependency>

Spring Boot  is a brand new application framework from Spring. It allows fabulously quick development and rapid prototyping (even including CLI ). One of its main features is to work from single "uber jar" file. By "uber jar" I mean that all dependencies, even an application server like Tomcat or Jetty are packed into a single file. In that we can start web application by typing java -jar application.jar The only thing we're missing is the managing script. And now I want to dive into that topic. Of course to do anything more than starting our application we need to know its PID. Spring Boot has a solution named  ApplicationPidListener . To use it we need to tell SpringApplication we want to include this listener. And there are to ways to achieve that.
